I believe all of the clubs consider stock to mean as the car might have left the dealer’s lot. By that definition LAT options and Sunbeam Factory Accessories are permitted. Again, I believe all the clubs agree on that.
By its very definition a “Concours d’ Elegance” means a competition of elegance, therefore condition and cleanliness are also judged. A well worn very original car would have trouble competing with a car correctly restored to original specs.
Recognizing this, we in TEAE have created a Rootes Preservation Class where cars are judged on originality ONLY. Cars are judged against a standard not other cars. We just added this class to our rulebook, so no feedback yet on how it actually works.
